public abstract class AbstractInMemoryThrottledSubmissionHandlerInterceptorAdapter
extends AbstractThrottledSubmissionHandlerInterceptorAdapter

Implementation of a HandlerInterceptorAdapter that keeps track of a mapping of IP Addresses to number of failures to authenticate.

Note, this class relies on an external method for decrementing the counts (i.e. a Quartz Job) and runs independent of the threshold of the parent.
